RAILROAD AUTOMATIC SIGNAL.

Specification of Letters Patent.

Patented June '7, 1910.

Application filed August 2, 1909. Serial No. 510,893.

To all whom it may concern:

Be it known that I, RmNHoLD RooHo'rsoI-I, a subject of the Emperor of Austria-Hum gary, residing at South Side Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Railroad Automatic Signals, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to alarm operating mechanism to direct the attention of an engineer on a locomotive to the presence of a semaphore signal when the latter through some cause is not visible and in this connection it will be stated that oftentimes, due to fogs and inclement weather, a semaphore signal when set to danger cannot be seen and oftentimes the engineer will run into or pass a block and which in some instances will cause wrecks and therefore it is the primary object of this invention to provide means in a manner as hereinafter set forth which is automatically operated at a point in advance of the semaphore signal to indicate to the engineer that he is nearing such signal; the warning will indicate to the engineer to stop his train so as not to run into or pass the block until after the danger signal indicated by the semaphore has been changed.

To the foregoing ends, the invention consists in the novel construction, combination and arrangement of parts for the purpose set forth in a manner as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views: Figure l is a diagrammatical view of a locomotive and further showing in side elevation an alarm operating mechanism in accordance with this invention, and, Fig. 2 is a front elevation of an alarm indicating mechanism in accordance with this invention showing the adaptation therewith of a locomotive and a semaphore signal, the tracks being in section.

Referring to the drawings by reference characters, 1 denotes a track, 2 a locomotive,

3 a signal post, 4: a semaphore, 5 operating means for the semaphore and 6 the engine Whistle.

Secured to the boiler casing or body of the locomotive are a pair of vertically extending supports 7 having flanged lower portions 8 which abut against the body of the locomotive or boiler casing and are secured thereto by the hold-fast devices 9. Formed integral with the upper terminus of the support 7 is a transversely extending elongated bearing sleeve 10 in which is mounted a transversely extending rock shaft 11 provided at one end with a crank 12, at its other end with a crank 13 and intermediate its ends with a crank arm 1a which projects through the sleeve 10. Connected to the lower portion of the boiler casing or body of the locomotive is a bracket 15 which supports a transversely extending bearing sleeve 16 in which is mounted a crank shaft 17 provided at one end with an elliptical shaped crank 18 and at its other end with an elliptical shaped crank 19.

The reference characters 20 and 21 denote vertically extending elongated links, the link 20 at its upper end being pivotally connected to the crank 12 and at its lower end is pivotally connected to the crank 19. The link 21 at its upper end is pivotally connected to the crank 13 and at its lower end is pivotally connected to the crank 18.

The whistle 6 is provided with a valve mechanism 22 adapted when actuated to sound an alarm and in this connection it will be stated that the stem of the valve mechanism is provided with an arm 23 connected by a link 24 to the crank 14. The shaft 11 in proximity to the crank 14 is furthermore provided with a crank 25 which is pivotally connected as at 26 to an elongated lock bar 27, the function of which being to maintain the valve mechanism in an open position to cause the sounding of the alarm, the mechanism being maintained in such position until the lock bar 27 is released. The lock bar 27 for a portion of its length is toothed as at 28 and extends through an angular lug 29, the wall of the opening through which the bar 27 extends is such as to allow the bar to shift toward the cab of the locomotive, such action taking place when the valve mechanism is shifted to open position, but said wall will not allow movement of the bar in the opposite direction, consequently maintaining the bar in the position shifted until the said bar is raised manually out of engagement with the wall, such action being had by the engineer after the alarm has been sounded.

The actuation of the shaft 11 to shift the cranks 12, 13, 1 1 and 25 is had by the passage of the crank 19 over the trip, the shaft 17 is rocked whereby the links 20 and 21 are elevated thereby actuating the shaft 11. k A bracket 30 is provided to limit the movement of the link 20, the bracket 30 being secured to the boiler casing or locomotive body.

The trip upon which the crank 19 rides is indicated by the reference character 31 and is adapted to be shifted in proximity to the rail 1 when the semaphore is set. The trip 31 is arch-shaped in contour and shiftably mounted in a flanged base 32 which extends transversely with respect to the track bed and at one side of one of the track rails as clearly indicated in Fig. 2 and is fixedly secured to the post 3. The width of the trip 31 is less than the length of the base 82 and the said trip has secured thereto an outwardly extending arm 33 which is pivotally connected as at 3% to one arm of a bell crank lever 35. The bell crank lever 35 is pivoted as at 36 t0 the post 3 and at its other arm. pivotally connected as at 37 to the actuating means 5 for the semaphore and by such construction, it is evident that when the semaphore is set to danger position the trip 31 will be moved against one of the track rails and in the path of the crank 19 so that said crank 19 will travel over the trip, sound the alarm so that the engineers attention will be called to the fact that the semaphore has been set to danger and under such conditions the engineer will stop the train and not run into or pass the block.

What I claim is:

1. A trip actuated signaling mechanism for railways comprising the combination with a trip mechanism, of a rock shaft mounted upon the locomotive and adapted to be automatically actuated by the trip mechanism, an alarm carried by the locomotive, a pair of crank arms carried by said shaft and extending in opposite directions with respect to each other, one of said crank arms connected to the trip mechanism for actuating the shaft, operating means for the alarm connected to the other of said crank arms, a third crank arm projecting from said shaft, and means connected to said third crank arm for maintaining the alarm in an.

operative position.

2. Trip actuated signaling mechanism for railways comprising the combination with a trip mechanism and a locomotive, of a bracket carried by said locomotive, a rock shaft mounted in said bracket and provided with a pair of crank arms, one of said arms connected with the trip mechanism for actuating the rock shaft, an alarm mechanism mounted upon the locomotive, an operating means for said alarm mechanism connected at one end thereto and at its other end to the other crank arm, a third crank arm carried by said shaft, and means connected to said third crank arm for maintaining the alarm mechanism in operative position.

In testimony whereof I afiix my signature in the presence of two witnesses.
